"This book contains translations of three ancient texts. The first is an explanation of the New Testament Book of Revelation (the Apocalypse) written by the sixth-century (CE) Christian scholar and monastic founder Cassiodorus. The second is a compilation of excerpts from the writings of St. Gregory the Great (died in 604 CE) on the Apocalypse. The original texts of both Cassiodorus and St. Gregory the Great are in Latin. The third text is a compilation of brief excerpts in ancient Greek from ancient writers who can be only tentatively identified on stylistic grounds. The identity of the compiler, too, is unknown. The manuscript of this third text was first discovered in 1911 in northern Greece"--
